XL Pulley tension wheel for Tacx Flux hometrainer

thingiverse

If the belt on your Tacx Flux is slipping under high load, it might be needed to replace the original pulley tension wheel with this XL version You can either buy brand new bearings, 2 bearings of type 6200-2Z is needed, or you should be able to reuse your existing ones. Some Tacx Flux also have problems with a tension arm made of plastic, which gets twisted after some usage, and then the pulley wheel has a wrong orientation. If that is the case, then don't use this wheel without fixing the problem with the arm, if you use this wheel with a twisted tension arm, then the problem gets even worse. For fixing a twisted tension arm, see several posts in the "Tacx Flux owners group" on facebook Wheel shall be printed with an infill of 70 percent to make it strong, and preferable with filament type PET-G or ABS. PLA filament is not a good choice, since it's less heat resistant, and the Flux gets fairly warm during usage
